Issues with Bootstrap 5 dropdown tabs

[cpsievert]

In this codepen, if you select one dropdown it'll 'activate' the other:

Also, note that the codepen uses the following markup:

<ul class="dropdown-menu">
      <a class="dropdown-item" href="#">Action</a>
</ul>

But, if you use the markup structure that the docs recommend, namely:

<ul class="dropdown-menu">
     <li><a class="dropdown-item" href="#">Action</a></li>
</ul>

Then you'll get other, different, issues with the .active class not being updated properly...
